LEBL Runway Assignments question

[Ray Proudfoot]

Hi Ricardo,

I'm using LEBL v1.0 in P3D v4.5. I have a question regarding the runway assignments. It was always my understanding that it is not possible to close only one end of a runway for landing or take-off. You have to close both ends or have them both open. That was the rule in FSX and remains the same in P3D as they use the same underlying code - ESP.

But looking at AFX_LEBL.bgl in ADE these are the runway assignments:-

Take-off only. 07R, 25L and 20.

Landing only. 07L, 25R and 02.

These would appear to break the rules of ESP. I've manually set winds to 080/15 and positioned myself near the 07R threshold. Aircraft are departing from this end but they are also landing which shouldn't be happening according to the settings in the AFCAD.

This is not meant as a criticism, just an observation.

Hi,

Thank you for your question.

I have just checked, and I did not see any aircraft landing on 07R nor 25L. Try to check to see if there isn't any other AFX file causing conflict. let me know

Hi Ricardo, I’m using the Alpha India Group Ai package which has a large number of flights. Maybe the number of inbounds causes both runways to be used. I’m also using a freeware package (AiController) that controls Ai and makes them fly SIDS and STARs which might explain the cause.

I’m pretty certain there is no other AFX file causing a clash. Were you aware of that runway closure rule in ESP? I wish it wasn’t there as many airports around the world have restrictions like EGCC 23L / 05R here at Manchester for which 05R is landing only and 23L is takeoff only. Any restrictions are just ignored by P3D where both ends are not the same.

Do your settings reflect real world ops? I was thinking of making the northerly runway at LEBL landing only (both ends) and the southerly take-off only. I’d leave 02/20 open both ends.

Hi, I have also AIG AI traffic.

Barcelona works this way, one runway for landings, another for takeoffs. I also wish they don't exist but those airports have local regulations based on noise complaints by the people who live nearby.

I use the same AIG type of AI traffic and don't get this problem. Its almost impossible that aircraft get assigned to a closed runway for landings, unless there is another AFX file causing this. Will further investigate.

Do your settings reflect real world ops? I was thinking of making the northerly runway at LEBL landing only (both ends) and the southerly take-off only. I’d leave 02/20 open both ends.

That's exactly how our AFX file works currently. though 02 is only used for landings and 20 for takeoffs.

Hi Ricardo,

The noise restrictions also apply to Heathrow and they switch landings during the day to give the residents some relief. But in a sim the residents don't really matter. I appreciate you're trying to reflect real world operations but the limitations in the ESP code don't permit that. I'm sure if you kept P3D running long enough you would see landings on 07R as I did.

Do you use ADE? When I use Find Faults for the LEBL AFD it reports lots of issues including stop locations and some altitude problems. I guess the stop locations are there to prevent aircraft taking off on some runways. A clean AFD would be good so do I need to worry about those issues?

Hi, I ran the sim on time acceleration and did not see them landing on 07R, would try in another time to see.

Thanks Ricardo. Maybe it's Ai Controller that is forcing them to use 07R.
